| The development of China’s automotive industry is one of the main factors have contributed to the development of the national economy, and its development is closely related to our economic development. Airbag for contemporary cars with seat belts as an indispensable security configuration can open in time to protect the lives and safety of the occupants when the car occur violent collision. However, in real life the airbag can not open in time or will pop up with slight collision, and these phenomena are closely related to the automotive airbag folding bags fault. Thus, the fault diagnosis of automotive airbag folding bags has important practical significance.On comprehensive the operating states and operating environment of airbag folding bag machine, using the configuration software combined system operating data developed fault diagnosis system for real-time control and feedback. This paper through analysis airbag folding bags unique failure, using a multi-sensor information collection theory, complete fault analysis features of each station. Combining the basic theory and method of BP neural network SOM, using motor fault, fold bag fault, tape fault, walk straight fault and truss fault as a sample, and using MATLAB neural network toolbox to the relevant parameters designing and get the expected output in line with the actual results, and completed the fault diagnosis of automotive airbag folding the bag machine.Under the theory of neural networks, this paper also combines the theory of expert systems, and the organic combination of the two methods, play to their characteristics, developed diagnosis expert System of automotive airbag folding bag device failure based on neural network. Equipment with programmable logic controller (PLC) as the control unit, and collect the signal data of systems, and then useing Lab VIEW to design the interface of the login and the main and the other. System interface is friendly and easy to operate, to achieve the monitoring and fault diagnosis of automotive airbag folding the bag machine.Through Fault Diagnosis of airbag folding bags can be efficiently carried out the production line assembly processes identify the fault category, can reduce the incidence of failure to further improve product quality, with a wide range of applications. |
